PLUG CONNECTOR Filed Feb. 20, 1961 INV ENT ORS V MORNEYS United States Patent O M 3,139,318 PLUG CONNECTOR Johann Binder and Rainer Buren, Wolfsburg, Germany, assignors to Volkswagenwerk Aktiengesellschaft Filed Feb. 20, 1961, Ser. No. 90,394 Claims priority, application Germany Feb. 23, 1960 3 Qlaims. (Cl. 339-258) This invention relates to a plug connector to a connecting standard or connector vane to make an electrical contact to an electrical element or device. It is at times necessary to connect a vane connector which is in turn connected to a safety fuze or instruments, to a plurality of wire leads or connections.

It is therefore an object of the invention to provide a connector which is adapted to be inserted into a plug or outlet or to the vane connector, with means to connect one or more lines thereto. A further object of the invention resides in a plug connector which may be connected to a plug connection in a perpendicular or angular direction relative to the plug connector so that it can be disconnected and again connected without the necessity of providing a soldered or welded connection. Advantageously the plug connector consists of a plurality of rolled-over side holding members which are to a certain extent springy or somewhat yielding to grip the plug vane and thus provide a secure connection.

Another advantage of this invention resides therein that two or more lead wires may be secured to the plug vane.

Further objects will be apparent from the following description when considered in connection with the accompanying drawing in which:

FIGURE l is an exploded View in perspective of the plug distributor or connector with a main plug standard and plug connector.

FIG. 2 is a cross section of the plug distributor,

FIG. 3 is a section taken on line 3--3 of FIG. 2 in the direction of the arrows,

FIG. 4 is a section taken on line 4 4 of FIG. 2 in the direction of the arrows, and

FIG. 5 is a side view partly in section of a modified structure showing a coupling between a plug vane and a pair of wire leads.

Referring to FIG. 1, a vane plug connector 1 is secured to and is in electrical contact with a connector plate A which latter is in electrical contact with a plurality of cartridge or plain fuzes (not shown). A plug distributor 2 is adapted to be connected to the plug connector 1 and includes two plug vanes or plates 3 and 4 integrally stamped out from sheet metal of copper or brass or other metals or alloys. This distributor 2 is provided with the two plates bent at an angle relative to the main connector base 2 and this latter has the two rolled side gripping members 9 as clearly illustrated in FIG. 1, and these 3,139,318 Patented June 30, 1964 ICS raised projections or holes 6 in the plug vanes 1 and 3. Thus an impression 5 cooperates to snap into a hole 6 or if the element 5 is raised it will snap into a depression 6.

As shown in FIG. l a cable B may be secured to the plug connector 7 which latter with its rolled edges may cooperate with the plug vane 3 as shown in FIG. 5 in interconnected relationship. Slots 8, FIGS. 2 and 3, may be provided in the plug connectors so that the connectors may be easily cleaned and also to provide an elastic connection of the parts.

FIG. 5 shows a pair of wires B connected to the distributor 2 and ultimately connected to the vane disc or plate 1 of the electrical device A, such as a fuze carrier or instrument of some type.

The assembly and operation of the connector distributor is believed to be obvious from the foregoing and the drawing in that with the structure it is possible to quickly assemble or connect or disconnect the wire leads for a fuze element, instrument, or other electrical device and with the gripping members it is possible to use the connectors in automotive vehicles and other apparatus where vibration is present.

As shown in FIGS. 2 and 5 the vanes 3 and 4 are generally U-shaped in side view and each end part of the U forms a connecting tongue for insertion into a pair of rolled over grip members.

We claim as our invention:

1. Plug distributor for electric plug connectors cornprising a plate of rectangular form and constituting a fiat base, spring grip clamps extending from one side of the base on two opposite edges thereof with the base extending beyond the ends of the spring grip clamps, and contact vanes projecting from the plate from the other side of the base and from the two other opposite side edges thereof, said contact vanes extending from the base with one vane forming an obtuse angle thereto and the other contact vane forming an acute angle thereto, said flat base on the side of the spring clamps being adapted to receive a vane plug thereon and under the spring clamps.

2. Plug distributor according to claim 1, in which the contact vanes project from the base plate in approximate parallel relationship and each spring grip clamp forms a rolled grip member.

3. Plug distributor according to claim 1, in which the plate with the contact vanes and the spring grip clamps are integrally produced from sheet material.
